Hi, I just updated my photoshop to 2025 and have noticed a considerable brush lag since the update. Normally I go to settings>preferences>deactivate native canvas rulers, but I don't see that option in 2025. Any advice on how to improve the brush lag?

Okay, try disabling the “Fast Startup” feature in Windows 11, which was the culprit of my Photoshop lag and is enabled by default, as it’s usually the case with most of Microsoft’s bad ideas.

Open the Control Panel, navigate to Power Options, click "Choose what the power buttons do," select "Change settings that are currently unavailable," and uncheck "Turn on fast startup (recommended)."

It’s supposed to boot computers faster, but it causes a lot of issues. Hopefully it works.

I am not sure that I have the same problem with you but you can consider trying uninstalling the wacom tablet driver.

Solution - updating PS reset the settings and turned on brush smoothing again.. turning this off (in brush settings) fixes the problem

This did not work for me. I did not have any issues until recently. It was working fine in April 2025, but I did not use it for a few months and in September (now) the brush is lagging no matter what I do.

Same here.. brush size 100px, 95% hardness, 1% spacing (although 25% spacing didn't make a difference).. it's been over a month since OP's original post.. no word from adobe?
